  • Okay folks, here's a look at the stocks that you are trading and the ones that are paying off--and the one's that aren't. The info is from Thursday's close. Some of the "usual suspects" are still on the lists but COMS seems to be a new player in the most active. PALM is one of the most active, but as you can see--not paying off that well. ARXT is making investors happy. Widely helds are pretty much what they have been lately. And FYI: Contest registrations to date: 415,962.

  • Good morning. Deborah Taft stays in the top position with a portfolio value of $2,187,663.68 for a gain of $2,000.00 or 0.09% from Thursday's action. Deborah was all in cash and received $2,000 in bonus bucks and has put the majority of her holdings into Elan Corp. plc (ELN) as of 3/22. (those bonus bucks from the trivia questions do add up!!)

  • James Tucker

    Actor Jonathan Tucker, from NBC's "The Black Donnellys" is in first place in the "Trading With The Stars" portion of our portfolio contest. He's been there for the week--and has a portfolio value of $1,030,700. But--as he told CNBC's Erin Burnett on the phone today, he's about to change his strategy.

  • Stephen Collins

    Actor Stephen Collins will be on "Morning Call" tomorrow to talk about his stock picks and strategy for "Trading With The Stars." So far, he's making a solid run with his third place standing. CNBC's Dylan Ratigan reported on Stephen's standing--including his gain yesterday (Wednesday) of some $24,000 or 2.4% for a total of $1,051,226 in his portfolio.

  • Question: What do Judy Gold, Stephen Collins and the Federal Reserve all have in common? Well, the answer is (sorry no bonus bucks) ....INACTION! As CNBC's Michelle Caruso-Cabrera pointed out--the Fed left interest rates unchanged Wednesday and the two celebs for "Morning Call" were unchanged in their positions in "Trading With The Stars."

  • Johnny Bench

    Johnny Bench--Hall of Famer, a key part of Cinncinnati's "Big Red Machine" baseball dynasty, successful business man. With all those accomplishments--can there be anything else to add to this man's resume? How about being out of last place in "Trading With The Stars?" Johnny's traded up to 9th place, changing places with actor Willie Garson.

  • Ernie Hudson

    Wow--did actor Ernie Hudson made a move or what Wednesday in "Trading With The Stars." He's now in 2nd place after making the biggest climb of any celeb trader so far. Ernie moved 5 places after being in 7th just the day before. How did he do it? Seems he sold all he had and is now strictly in cash. Will that strategy hold? Remains to be seen.

  • Here's a look at what stocks were active, good and bad, on Wednesday's close. FMT remains popular with contestants--with apparent good reason, as you can see on the return percentage listings. The subprime "crisis" real or not-may be effecting buys. CMGI, REV and SIRI remain among the most active and widely held. Registered contests: 394,948.

  • Hello. There's a new leader on top this Thursday morning. It's Deborah Taft, with a portfolio value of $2,185,663.69 with a gain of $302,686.98 for a 16.07% increase.  Deborah had the majority of her holdings in Fremont General (FMT) which was up 10.19 +1.41 (+16.06%). She made the jump from 3rd to 1st.
